If your skin has been feeling tight, flaky, reactive, or simply feeling a little “off,” the best barrier repair serums can make a big difference. Unlike exfoliating or brightening serums that focus on changing the surface, these formulas work on prioritizing comfort and recovery over instant glow. “The skin barrier contains lipids and ceramides that create a protective barrier against external stressors,” says Christina Sun, MD, a board-certified dermatologist based in Philadelphia. When it’s functioning well, you barely think about it. When it’s not, your skin makes that loud and clear.
Our Top Barrier Repair Serums
Many things can chip away at the skin barrier. Sometimes it’s the routine itself: Dr. Sun explains that “when this barrier is weakened by over-cleansing or the use of harsh active ingredients, the skin can become dry, irritated, and inflamed.” Also, if you’ve ever layered retinoids, acids, and vitamin C with a little too much enthusiasm, you know how fast the barrier can call an SOS. But it’s not just actives—cold weather, low indoor humidity, and even too-hot showers can make things worse.
Barrier repair serums are designed to rebuild what’s been depleted so the skin can calm down, stay hydrated, and tolerate actives again. “Barrier repair focuses on restoring these natural components and using gentle skincare practices that help maintain hydration and support overall skin health,” Dr. Sun explains. Think of these serums as the peacekeepers of your routine.
Frequently Asked Questions
Best Overall: SkinCeuticals Hyaluronic Acid Intensifier Multi-Glycan Serum
Why it’s worth it: If you were a SkinCeuticals loyalist who swore by the (now-discontinued) H.A. Intensifier, consider this the souped-up sequel. The 2024 Best of Beauty Award-winning Hyaluronic Acid Intensifier Multi-Glycan Serum still incorporates deep hydration that softens fine lines and facial folds, but now with even more dimension. The formula keeps the star ingredients from the OG—hyaluronic acid for hydration, licorice root for brightening, and purple rice for antioxidant support—and upgrades them with Proxylane, the brand’s proprietary post-biotic ferment extract (a nutrient-rich byproduct of fermentation that helps replenish the skin and support a healthy microbiome). By boosting glycan levels, which are the complex sugars behind skin’s natural springiness, Proxylane “doesn’t just make skin look plumper and more elastic; it contributes to better barrier function, too,” says Dr. Sun. In addition to intense hydration, “it helps strengthen the skin barrier and improve moisture retention over time,” she says.
Tester feedback from Allure commerce editor Sarah Han
“I don’t love most HA serums but SkinCeuticals—as it often provdes to be—is the exception. It’s supremely silky (it kinda reminds me of snail mucin, but much more pleasant and fast-absorbing!) and gives my skin an instant plumping effect. I love pairing it with my antioxidant and retinol serums for the all-day or all-night hydrating boost my skin usually desperately needs, especially in the colder months. I’d be lying if I said I didn’t find the pink color very pretty…and also kind of surprising for such a serious brand!” —Sarah Han, Allure commerce editor
- Key ingredients: hyaluronic acid, Proxylane, lactobacillus/soybean ferment extract
- Fragrance-free: yes
Best for Dry Skin: The Inkey List Ectoin Hydro-Barrier Serum
Why it’s worth it: The Inkey List’s Ectoin Hydro-Barrier Serum keeps things refreshingly simple here with a straightforward ingredient list. It features 2% ectoin, which helps your skin hold on to moisture and stay calm in the face of everyday stressors (think indoor heaters, wind, pollution), while 2.5% multi-molecular hyaluronic acid brings hydration to different layers of the skin’s surface. Using multiple molecular sizes means you get that instant plump, dewy feel on top and longer-lasting hydration beneath—a noticeable improvement over the quick-hit hydration that regular HA provides. A 1% barrier blend with three ceramides (plus helpful lipids like cholesterol and phytosphingosine) reinforces the skin’s protective barrier and reduces water loss. The lightweight, non-greasy texture makes it easy to slot into a routine on its own or under makeup.
“My dry-skin routine, which includes tretinoin, wouldn’t be complete without this serum. Two pumps is just enough of the cloudy formula to cover my face and neck. It glides on effortlessly and dries quickly, leaving my skin feeling slightly tight—but not in a drying way. It feels taut and smooth, and my dry patches feel quenched. Layered under a moisturizer, the feeling disappears immediately.” —Jesa Marie Calaor, Allure senior beauty editor
- Key ingredients: 2% ectoin, 2.5% multi-moelcular hyaluronic acid, ceramides
- Fragrance-free: yes
Best Drugstore: La Roche-Posay Hyalu B5 Hyaluronic Acid Serum
Why it’s worth it: Hyaluronic acid is a crowd favorite for plump, glowy, deeply hydrated skin, particularly if you have sensitive skin. La Roche-Posay’s Hyalu B5 Serum incorporates two forms of the ingredient to draw moisture into the skin, plus madecassosides (the wound-healing compounds from Centella asiatica), which help reinforce the barrier, and vitamin B5 helps calm and hydrate. Despite the wallet-friendly price point, “the blend of panthenol, hyaluronic acid, and soothing agents repairs the barrier so quickly and efficiently that it rivals medical-grade products,” says Cheryl Karcher, MD, a board-certified dermatologist based in New York City. The lightweight gel sinks in fast, plays nicely with every skin type, and leaves your face looking smoother, bouncier, and just plain dewier.
“There are few skin issues in my life that a good hyaluronic acid serum can’t fix. Dry patches? Hyaluronic acid. Dull skin? Hyaluronic acid. Clogged pores? You wouldn’t think it, but hyaluronic acid genuinely helps balance my skin so it’s not producing the excess oil that pisses my pores off. La Roche-Posay’s Hyalu is the platonic ideal of an HA serum to me: medium viscosity, non-sticky, and vaguely aquatic-smelling. My skin is always better off when I make the time to stack it in ahead of moisturizer.” —Sarah Hoffmann, Allure commerce producer
- Key ingredients: hyaluronic acid, madecassoside, glycerin, vitamin B5, La Roche-Posay Thermal Spring Water
- Fragrance-free: yes
Best for Sensitive Skin: KraveBeauty Barrier Relief Serum
Why it’s worth it: KraveBeauty’s Barrier Relief Serum takes its inspiration from a classic Korean skin-care philosophy: Less is more. Instead of piling on actives, this creamy serum focuses on replenishing what over-exfoliation, harsh cleansers, or environmental stress tend to take away. Tamanu oil brings soothing, barrier-mending benefits, plus gives the formula a natural green tint thatsubtly neutralizes redness (though it won’t color-correct like makeup). Niacinamide helps smooth tone and strengthen the barrier over time, while rosehip and safflower seed oils offer lightweight nourishment. Squalane and sodium hyaluronate help maintain hydration levels, and oat and ceramides deliver that calm, comforted feeling your barrier is likely craving. It also has the stamp of approval by the National Eczema Association’s stamp of approval, which is always nice to see if your skin tends to be reactive or easily irritated.
Tester feedback from Allure associate beauty director Sarah Kinonen
“My favorite way to use hydrating serums, like the KraveBeauty Great Barrier Relief, is the ‘sandwich method.’ Essentially, I’m just layering the serum under and over my prescription topicals, creating a barrier in-between my actives and easily sensitized skin. I like the Great Barrier Relief because it’s super lightweight, blends and dries quickly, and is formulated with soothing ingredients like tamanu oil, ceramides, and niacinamide to cut irriation before it happens. Plus, it’s from a small business, and I love supporting indie brands!” —Sarah Kinonen, Allure associate beauty director
- Key ingredients: 10% tamanu oil, niacinamide, ceramides
- Fragrance-free: yes
Best Night Serum: Estée Lauder Advanced Night Repair Synchronized Multi-Recovery Complex Serum
Why it’s worth it: While you won’t find retinoids or other ingredients that make skin more sun-sensitive, Estée Lauder Advanced Night Repair Synchronized Multi-Recovery Complex Serum is designed to be used distinctly at night because that’s when skin naturally shifts into repair mode. The formula relies on fermented ingredients such as Bifida ferment lysate, yeast extract, and Lactobacillus ferment to support the skin’s microbiome and strengthen the barrier after daytime exposure to stressors. Hydrators like glycerin and sodium hyaluronate pull in moisture, while squalane, lecithin, and jojoba esters help seal it in. It also includes a patented tripeptide-32, which is meant to sync with skin’s circadian rhythm to support overnight renewal. Add in soothing ingredients like bisabolol and chamomile, and you might just believe that beauty sleep in a bottle exists.
Tester feedback from Allure senior commerce editor Sarah Felbin
“If I could only use one serum for the rest of my life, it would be this one. I use it every morning and every night, and I absolutely notice when I skip a day. It feels so lightweight and nourishing, sinking in quickly without leaving a sticky residue behind. In addition to the nice glow it gives me, it calms my super-sensitive skin, prevents pesky flakes in the chronically dry spots around my nose, and keeps breakouts at bay. Pricey? Yes. Worth it? You bet!” —Sarah Felbin, Allure senior commerce editor
- Key ingredients: peptides, hyaluronic acid, Bifida ferment lysate, Lactobacillus ferment

Best Budget: The Ordinary Soothing & Barrier Support Serum
Why it’s worth it: The milky pink tint makes it look sweet, but the formula is all business when it comes to calming cranky skin. The Ordinary Soothing & Barrier Support Serum “is a straightforward, accessible option that focuses on hydration and barrier support without unnecessary additives,” says Dr. Reszko. Key ingredients include niacinamide to help regulate inflammation and reinforce the barrier, along with multiple forms of Centella asiatica (asiaticoside, asiatic acid, and madecassic acid) and bisabolol to visibly reduce redness and sensitivity. To rebuild the barrier more directly, the serum also incorporates skin-identical lipids such as sphingolipids and sterols, plus panthenol for long-lasting comfort and hydration. “The lightweight formula layers easily and is suitable for daily use across most skin types,” adds Dr. Reszko.
- Key ingredients: Centella asiatica, bisabolol, niacinamide, ceramides
- Fragrance-free: yes
Best for Acne-Prone Skin: EltaMD Skin Recovery Serum
Why it’s worth it: It makes sense that one of our favorite brands for sunscreen (arguably the ultimate way to protect the skin barrier) also makes one of the best formulas for repairing it when things go awry. According to Anetta Reszko, MD, a board-certified dermatologist in New York City, oily or breakout-prone skin is especially prone to barrier disruption from acne treatments or over-cleansing. “EltaMD’s Skin Recovery Serum supports barrier recovery and visible redness reduction without clogging pores,” she says. The formula tackles a stressed barrier with the brand’s proprietary amino acid blend to reduce redness and minimize irritation while boosting hydration. Centella asiatica reinforces the barrier’s structure, sodium hyaluronate delivers lightweight moisture deeper into the skin’s surface, and panthenol (vitamin B5) soothes sensitivity.
- Key ingredients: amino acids, Centella asiatica, tocopherol, hyaluronic acid, panthenol
- Fragrance-free: yes
Best for Mature Skin: BioEffect EGF Power Serum
Why it’s worth it: Most barrier serums spend their time replenishing ceramides, fatty acids, and cholesterol so the skin can hold on to moisture. BioEffect EGF Power Serum takes a different approach by using plant-derived growth factors such as barley EGF (epidermal growth factor) and KGF (keratinocyte growth factor) to help skin cells “talk” to each other more efficiently and behave more like younger skin. These growth factors act as the skin’s own signaling proteins for collagen and elastin production and even skin repair, so you’re getting benefits that go deeper than surface hydration. “Mature skin often shows fine lines more prominently when the barrier is depleted. This serum supports skin renewal while improving hydration and overall resilience,” says Dr. Reszko. And if uneven tone is on your radar too, the formula also includes N-acetyl glucosamine, an amino sugar that reinforces the barrier while helping brighten over time.
- Key ingredients: plant-based growth factors, glucosamine, hyaluronic acid
- Fragrance-free: yes
Best Fragrance-Free: Dr.Jart+ Cicapair Intensive Soothing Repair Serum
Why it’s worth it: By now, you might know that K-beauty is practically synonymous with calming Centella asiatica, but ingredients like allantoin and madecassic acid still tend to fly under the radar. Dr. Jart’s Cicapair Intensive Soothing Repair Serum puts both to work for anyone dealing with sensitivity, irritation, or a barrier that’s just had enough. “Allantoin supports that process by helping moisturize and reinforce the barrier,” says Dr. Sun. Meanwhile, madecassic acid helps create calmer, less-inflamed conditions in which the barrier can repair itself more efficiently. “This serum’s also great for sensitive types because it’s fragrance-free and alcohol-free, which are common triggers for reactive, sensitive skin,” Dr. Sun adds.
- Key ingredients: Centella asiatica, allantoin, madecassic acid
- Fragrance-free: yes
Frequently Asked Questions
How is a barrier repair serum different than a barrier repair cream?
A barrier repair serum delivers targeted ingredients that help strengthen the skin’s protective function and improve moisture retention below the surface. “These formulas are typically lightweight and absorb quickly, making them ideal for supporting the barrier beneath other skincare steps,” says Dr. Reszko. A barrier repair cream, on the other hand, focuses more on sealing and protecting at the surface by locking in hydration and preventing water loss. “In practice, serums help rebuild the barrier, while creams help shield it, which is why pairing the two often works best,” she says.
Who should use a barrier repair serum?
Barrier repair serums aren’t just for people with dry or temperamental skin. As Dr. Reszko explains, “barrier repair serums can benefit nearly all skin types and are especially helpful for those experiencing dryness, sensitivity, or irritation.” They’re also useful for anyone using retinoids, exfoliating acids, or acne treatments, which she notes “can temporarily weaken the skin barrier.” By strengthening and supporting the barrier, the skin is better able to tolerate active ingredients and maintain balance.
Can you overuse skin barrier repair serums?
Yes, you can overdo it. Dr. Reszko notes that “it is possible to overuse barrier repair serums, particularly when layering multiple reparative or hydrating skin-care products.” When you overload the skin with similar functions, it can interfere with the skin’s natural ability to self-regulate. In most cases, she adds, “a single well-formulated serum used consistently is more effective than layering several similar products.”

How we test and review products
When Allure tests a product, our editors look at it from every angle in an effort to best serve you. We review ingredients, scrutinize brand claims, and, when necessary, examine peer-reviewed scientific and medical studies. In addition to testing each and every product that’s included in each and every review, we rely on experts who shape their fields, including dermatology, cosmetic chemistry, and medicine, to help us vet the ingredients and formulas.
For our list of the best repair serums, we considered each product’s performance across five primary categories: product ingredients and efficacy, packaging, fragrance, texture, and product wear. Every product was determined to have excelled in each category by our editorial team of in-house writers and editors, as well as contributors, along with special consideration from dermatologists. To learn more about our reporting and testing processes, read our complete reviews process and methodology page.
Our staff and testers
A beauty product is a personal purchase. You might be searching for a face cream to address persistent dryness or a new nail product to add to your Sunday self-care routine; you may simply be browsing around for the latest launches to hit the hair market. No matter what you seek or your individual needs and concerns, Allure wants to ensure that you love anything we recommend in our stories. We believe that having a diverse team of writers and editors—in addition to the wide range of outside testers and industry experts we regularly call upon—is essential to reaching that goal.
After all, can we really say a skin-care product is the “best” for people over 50 if the only testers we’ve solicited opinions from are folks who have yet to hit 30? Can we honestly deem a high-end diffuser worthy of your hard-earned cash if it’s never been tested on curls? We’re proud that our staff spans a wide range of ages, skin tones, hair textures, genders, and backgrounds, which means that we are able to fairly assess any beauty product that comes into the beauty closet.
